Answer:

(A) h(x) = 1/4x -2

Step-by-step explanation:

Given: f(x)=4x+8

Rewrite with y: y=4x+8

Switch x and y: x=4y+8

Solve for y: x-8=4y

(x-8)/4=y

1/4x-2=y

y=1/4x-2

This means that h(x) = 1/4x -2 is the correct answer

Solve the following equation for q. 5q + 2p + 4 = 3q – 8.

Yuri [45]

Answer:

Step-by-step explanation:

$\\$ By collecting the like terms , we have:

$\\$ 5q - 3q = - 8 - 4 - 2p

$\\$ 2q = -12 - 2p

$\\$ divide each term by 2 , we have

$\\$ q = -6 - p

what is a correct first step in solving the inequality –4(3 – 5x)≥ –6x 9? –12 – 20x ≤ –6x 9 –12 – 20x ≥ –6x 9 –12 20x ≤ –6x 9 –1

suter [353]

we have

$-4(3-5x) \geq -6x+9$

Step 1

Applying the distributive property in the left side ( Multiply the factors on the left side)

$-4(3-5x) \geq -6x+9\\- 4*3+4*5x\geq -6x+9\\-12+20x\geq -6x+9$

therefore

<u>the answer is</u>

$-12+20x\geq -6x+9$
